    1. Go to Device -> device settings -> SIP normalization script
    2. Click AddNew
    3. Click Import File and upload the attached file
    4. Enter a name, such as “DiscardIncoming180Ringing”
    5. Click Save
  3. Go to  Device -> Trunk
  4. Find and edit SIP Trunk for QME
  5. Within “SIP Information” section, find “Normalization Script”
